چکیده

Using a very simple flow cytometry protocol, we found that CD36 and CD117 on granulocytes and CD56 on monocytes were the major bone marrow phenotypic aberrations in patients with myelodysplasia, including CMML. CD56 on monocytes was associated with CMML. Importantly, phenotypic aberrations were lost on blood cells, except for CD56.

Range Determination of Antigen Expression in Myeloid, Erythroid and Lymphoid Cell Lineages among Patients with Myelodysplastic Syndrome

Background: Myelodysplastic syndrome is a mixed clonal disorder of bone marrow progenitor cells. Understanding the pattern of the different lineage-specific, immature, and mature markers in myelodysplastic syndrome will help in setting-up the frame of reference to diagnose. Patients and Methods: We compared 60 bone marrow samples from 30 newly-diagnosed patients with myelodysplastic syndrome ...

Multicentric study underlining the interest of adding CD5, CD7 and CD56 expression assessment to the flow cytometric Ogata score in myelodysplastic syndromes and myelodysplastic/myeloproliferative neoplasms.

Although numerous recent publications have demonstrated interest in multiparameter flow cytometry in the investigation of myelodysplastic disorders, it is perceived by many laboratory hematologists as difficult and expensive, requiring a high level of expertise. We report a multicentric open real-life study aimed at evaluating the added value of the technically simple flow cytometry score descr...

Relative contributions of enzyme cytochemistry and flow cytometric immunophenotyping to the evaluation of acute myeloid leukemias with a monocytic component and of flow cytometric immunophenotyping to the evaluation of absolute monocytoses.

We evaluated the contributions of enzyme cytochemical stains and flow cytometric immunophenotyping (FCI) data to detection of monocytic cells (MCs) in acute myelomonocytic and acute monocytic leukemias (AMMLs and AMoLs) and compared FCI findings in AMoL, chronic myelomonocytic leukemia (CMML), and normal peripheral blood (PB) and bone marrow (BM) monocytes to classify and evaluate absolute mono...

Immunophenotypic features of granulocytes, monocytes, and blasts in myelodysplastic syndromes.

BACKGROUND Despite the diagnostic utility of immunophenotyping for myelodysplastic syndromes (MDS), it has not been widely performed, and reports on this are absent in Korea. We aimed to evaluate the immunophenotypic features of non-blastic granulocytes, monocytes, and blasts in patients with MDS and non-clonal disorders using routine flow cytometry (FCM). Moreover, we evaluated the phenotypic ...

Flow cytometric assay for the evaluation of phagocytosis and oxidative burst of polymorphonuclear leukocytes and monocytes in myelodysplastic disorders.

BACKGROUND Myelodysplastic syndromes are clonal diseases characterized by pancytopenia of variable degree. Neutropenia is common and several morphologic and functional abnormalities of polymorphonuclear neutrophilic granulocytes (PMNs) and/or monocytes have been described. On the basis of these observations, the phagocytic and oxygen intermediates production of PMNs and monocytes was determined...
